Answer:
Possible expressions are:
8x
8 * x
8(x)
8 · x
Answer:
D. 13
Step-by-step explanation:
x = 5
2 x 5 + 3 = 13
5 + 8 = 13
meaning the side length has to be 13, also.
If n = number of hours and the equation is 174 + 58n then the answer is 3 hours
174 = 58n
÷ 58
3 = n
No
for example (question 1),
3(2a - 5) you multiply the numbers inside the parenthesis ().
so it will be 6a - 15
And if there is a negative number in front of the parenthesis, you multiply that too
-1(2x-5) will be -2x+5
negative times negative will be positive!
